Conditions at Merimbula Bar in January
January: Peak Summer Slop
Merimbula Bar is locked in the summer trade-off in January. The average swell height is a tempting 5-6ft (1.5-1.8m), but the average 8.1s period is all windswell and short-range energy. The wave rose is dominated by NE (19.6%) and ENE (14.6%) swells, while the SE/SSE/S/SSW quarter that lights up the Bar contributes just under 34%. That means many days deliver fat, sectiony NE windswell rather than clean groundswell.
Wind tells the real story. Ideal offshores from N, NNE, NW and NNW only blow 22% of the time, while the onshore S/SSW flow combines for close to 24% and often follows the warmest afternoons. With air temperatures around 20.2°C, water at 20°C and 2.4mm of daily rain, summer styles rule. Keep an eye on early mornings before the seabreeze kicks in, or the occasional Tasman Sea low that can swing the swell SE and align with a rare offshore N/NW flow.
